My predecessor set up Tomcat 6 on a RHEL5 server and it's logging to /var/log/tomcat and creating log files like catalina.2012-11-28.log (catalina.date.log) - how do I change the log format from date to catalina.1.log, catalina.2.log, etc.? The server.xml does not contain any references to logging, the only place I see is in logging.properties. How do I change the behaviour of Tomcat's logging?
